To 'all whom t may concern.'

-Be it known that I, EARL II. COOK, a-citizen of thel United States, and a residentof atertown; in the county of Jefferson and 5,? State of".VVisconsin,` have invented a new and usefulV Improvement in Table-Slide Cony struetions, of which thefollowing is a full, g ;`c l ear andy exact description.

` My/ inventionrelates.toimprovements in" .table vslide vconstructions for Jfolding tables, andit consists in the combinations, constructions,and arrangements herein described and claimed vn object of my invention is to provide tableslide construction in which the sliding :rnembershave L-groovesso constructed as to lprovide the maximum amount of supporting Ysurface tothe plates connectingthe members together 'Arfurther Object of my invention is. to providefa ,device ofthe character described in ...berstogether are lsecured tothe members in 4.a novelway. '-25 Aurther object of my invention is toprovide a device of the characterdescribed in' l features 'of the invention will be particularly pointed out in the appended claims.

In vcarrying outmy invention. I provide Sl'ldillgifmembers 1; 2, and 3, each of which l define T-shaped portions 8. The member 1 has a connecting` plate15 ,disposed at oneend ,-whichxthe plates securing the sliding mem As shown in Figure 3,the sliding member 1 `l..shaped portionsfoflthe grooves 5. wl\/ .'[y invention is illustra-ted inthe accomp-v that the member 1 is suppo-rtedby the maxsince the outer surfaces of thegrooves 5 bear i the plate 15. The members 1 yare. `a lso Figure 5 .-isra -side eleva-tion .of a connect- :.Larelprovidedawth L-shepedgrooves :therein- The vmember 1 is provided with li..shaped grooves 4 the member 2 is provided with L-shaped grooves 5 on one of its sides and with grooves 6 on its other side, Vand the,60 Y

member* is provided with grooves '7. In Fig1ire3,"theshape ofthe grooves is clearly7 shown, and 1t will'be noted that the grooves thereof (see Figures v4 and slot 10 is cut parallel with the bottom of `the grooves 4,' and is adapted to receive the plate 15'. 'The v plate 15 is provided with a slot 11 therein through which the screw 12 is disposed, kthe 70 screw being adapted to prevent the withdrawal ofthe member 15, and at the same time, to permit a slightpmovement of the member 15 with respect thereto. Itis ob-y viou's that the slot 10'may be of any desired '75 depth so` as tope-rmit movement of the'plate ,'15 with respect to the screw 12. 'The plate y 15'` extends to the outer sidespof the grooves 4 and is"4 then bent at rightA angles' so'as 'to project laterally from the grooves. The 80 plate 15 is' again bent at right angles so as i to provide two inwardly'projecting lugs 13 and 14 fora' purposev hereaiter"`desc`ribed. The portions oi" rthe plate 15l parallel )with the outer sides of thef'grooves 4 are of the same width as the depth of theigrooves 4.

It will therefore be apparent tlhat'the lugs 13 and 14 ,will abutf'the inner surfaces of the grooves in theadj acent sliding member.

Asheretofore stated/,v` the member 1 isslidi ably connect-ed tofthememb'er'2by mea-'ns of connected `to each otherby means Vof 1a plate ,9 Awhich-islidentical to the.p'l'atepl'` Inhlike 1nanner, the member 2 :.member. 2. InlFigure 2, the members 1, 2,

are shownin extended: position and eerie! l are prevented from any further movement in an outward direction by means of strips 18 (see Figure 4i), which are disposed in the grooves 5 and 6, respectively, and abut against the adjacent edges of the plates 9 and 15, and 16 and 17, respectively. The member 2 is rigidly secured to a cross piece l) of the table, which in turn is carried by a pedestal Q0. lVhen the table is made smaller, the leaves 21. are removed from the table and permit the two table sections 22 to be brought together. Movement of the sections 22 toward each other also moves the meinbers 'L and 3 inwardly. since the sections Q2 are rigidly secured to the. members 1 and 3. lt is obvious that twosets of members 1, 2, and 3 are used in each table. l. and are prevented from further movement when the two members are alined with the member 2, As clearly shown in Figures 2 and 4, the members 2 and 3 carry pins 23 and 24 which are adapted to be received i n slots 25 which are disposed in the ends of y the members 1 and 2.

From the foregoing description of the va rious parts of the device, the operation thereof may be readily understood. As heretofore stated, the Lshaped grooves in the members are so disposed that the outer walls thereof have the greatest amount of surface with respect to the other walls of the grooves. The connecting plates are adapted to bear against the outer surfaces of the grooves and to thus provide the greatest amount of supporting surface between adjacent members. The connecting plates are readily adjustable with respect to the sliding members, since they are secured to the members by means of screws which are diposed in slots in the connecting members. It will therefore be seen that a line adjustment may be had between the adjacent sliding members so as to cause them to perfectly aline with each other when they are in closed position.

In Figure 6, I have shown a slightlyl modified form of the connecting plates. This connecting plate 26 could be used in place of the plates 9 and 17 in the preferred form of the device. clearly shown .in the drawing, the outwardly extending portions of the plate 9,6 are bent upwardly so as to provide supporting surfaces 27 to the adj a cent member which are at a higher elevation? than are the outer surfaces of the L-shaped grooves to which the plate 26 is attached. lilith this construction. it will be apparent that the outer ends of the members 1 and 3 f are tilted slightly upwardly with respect to the member 2. since the plates 26. which take the place of the plates 9 and 17, would slightly raise the members 1 and. 3 above av The members but the outer ends of the members 1 and will have to swing or move an appreciable' v distance before -theywill pass the position which is horizontal with the plane of the member 2; l

From the foregoing, it will be observed that l have providedy ay simple table slide construction which makes use of the greatest Stil amount of support-ing surface bett 1'een the sliding members. l also provide a connecting plate of novel construction which isadapted to securely connect the adjacent sliding members together and to prevent any lateral movement of the memberswith respect to each other. It will be seen thatV the connecting plates preventvany lateral movement between the sliding members, since-they abut the outer and bottom sides of the L-shaped grooves. l also provide a means by which the ends of theftable are prevented from sagging when slightly worn or when a relatively great weight is placed thereon. As heretofore stated, the ,device is simple in construction .and is efiicient for the purpose intended. n f l y l Iclaim:y M
